摘要： The invention relates to a magnetic resonance imaging method which is characterized in that the transversal magnetization excited in the object to be imaged is diffusion-weighted before the useful echo (E) used for the reconstruction of an image is induced. When the object is moved, phase changes in the diffusion-weighted transversal magnetization can occur that lead to artifacts in the reconstructed image. These disturbing phase changes are measured by analyzing a navigation signal (N1, N2) that is generated before the useful signal is generated. The result of the measurement is used to change the phase characteristics of the transversal magnetization online by a correctional intervention (C0, C1, C2) in such a way that the measured phase changes are compensated. The invention further relates to a magnetic resonance device for carrying out said method.

摘要： The invention relates to an HF-antenna system for carrying out and/or detecting a magnetic resonance in an object exposed to a main magnetic field which orients the object spins in a desired longitudinal direction (z) comprising at least one first antenna element (1) provided with several conducting sections (11, 12, 13, 14) which lead a high-frequency alternating current and extend from the common top to a base area in the form of separate claws in such a way that the testable object containing a volume of interest is enveloped in a helmet manner. Said invention is characterized in that each conducting section (11, 12, 13, 14) is embodied in the form of a HF (HL) line for electromagnetically connecting a wave propagating in a TEM mode or in an quasi-TEM mode with the spins of the testable object to be enveloped and the electrical length the terminals of the HF (HL) lines are selected in such a way that the magnetic resonance frequency waves are produced therein.
